Unintended router operations via cross-site requests
Published Feb 3, 2026 · Updated Feb 3, 2026
Cross-site request forgery in ELECOM WRC-X1500GS-B and WRC-X1500GSA-B 1.12 and earlier allows attackers to perform unintended operations. ELECOM has not published the affected management endpoint or the exact request-validation failure that accepts the forged request. Exploitation requires a logged-in administrator to visit an attacker-controlled page; the documented consequence is limited to unintended router operations.
